This paper presents a practical technique to design/improvement the existing Thailand crude storage tanks system from manual valves to automatic control for decrease the operator waste time by using programable logic controllers (PLCs) interface to the main controller (DCS) of the existing system via using Profibus protocol mapping data to control motor-operated valve (MOVs) which upgrade from existing system which uses manual valve operate by the operator. The controlled MOV utilized follows a recipe from a master controller for mixing crude oil from each tank and feeding it to the header after this supply to the refinery process. The proposed technique is based on the use of Profibus protocol to manage data to control MOVs by using PLCs modeled B&R X20CP3586 for interconnections of four nodes through Profibus master modeled B&R X20IF1061-1 for twelve slaves, eighteen slaves, fifteen slaves and two slaves for each node, and master controller over a control network to communicate between master control (DCS) with PLCs through DP/DP couple modeled Siemens SIMATIC DP 6ES7158-0AD01-0XA0 working as a Profibus gateway. Input status and output command of each MOV valve are sent/receive and controlled by the PLCs are specified with command and status byte for cyclic communications. The proposed PLC control system for control of the MOV valve can operate following the manufacturer"s requirements with fast response and more reliability.
